ICE-Runnin.

SPECIFICATION forming part of Letters Patent No. 303,287, dated August12, 1884.

` Appncmim inca March 4, resi. (No morini To all whom it may concern,.-

Be it known that I, EDWARD S. HUNN, n. citizen 0f the United States,residing et Kala.- nmzoo, county of Kalamazoo, State of Michigan, hereinvented :i new and useful Iee-Itub ber, of which the following is aspecification.

My invention consists in Certain improved features of constructionhereinafter described and claimed.

In the drawings forming a. part of this specification, Figure l is a.side elevation of n. rubber shoe, the soie and heel being in sections,Showing the construction; Fie. 2, it brokenv horizontnlsection of theshoe-*sole enlarged; and Fig. 3 is e perspective view of a spur.

The sole of the rubber is provided, when inzrnnfnetnrin'g it; withspur-holes imving n, countersnnk recess t the upper end adapted toreceive the heeded spur A, Fig. 2. These spurs are pointed et the lowerend, Where they extend through the sole. The inner lining, I3, of thesole forins a. cover to the heads of ther spurs Afnnd prevents saidspurs from pushing up out of piece when `trod upon by the wearer. Thelining B, in inanfneturing the rubbers, is cemented in.

In the ninnniirctnre of this class of rubber goods, especial lines nin-ybe provided with the spurs with e view te the especial use set forth.The spurs :ire innde as long as th e uncontraeted sole is thick. Thusthe points of the spurs do Wirren not sustain the entire weight of thewearer. The pressure ofthe foot upon the rubber tends to force the)oints of the r4spursthrough Iie eins icwsoles end`1"it` `tli"iee orfrozen snow.

tliespurs are shown when not under pressure of the foot; and in Fig. thespurs nre shown forced through the sole, :is when engaging the ice.

By providing the sole With the spurs when inanufneturing the goods, 'therubber is just :is useful for its originel purpose, and but littleexpense'is added, and the rubber never slips, es do the c'oinnion style7after they are nflittlc Worn on the bottoni.

Having thus described my invention, what I claim is- A rubber foot-Weerprovided in the elastic sole thereof with spurs having their pointedends extending to the lower surface only, and

their headed ends countersunk und covered by the cemented inner sole,whereby the spurs aire adapted to be forced down into the iee by thepressure of th'e foot upfn the sole, substentinlly as set forth. 4

In testimony of the foregoing I have here unto subscribed my nume in thepresence of two Witnesses.
